FRS-R-6-1/4 is a Fusetron™ 600 V Class RK5 dual-element, time-delay fuse rated at 6.25 amperes with a voltage rating of 600 Vac and 300 Vdc. This advanced, energy-efficient fuse provides current-limiting protection with a 10-second minimum time delay at 500% of rated current, enabling closer sizing and superior protection of motors and transformers. The fuse features a 200 kA interrupting rating for Vac and 20 kA for Vdc, delivering motor overload, ground fault, and short-circuit protection while limiting let-through current to protect downstream components. Its dual-element design allows for smaller fuse and switch ratings, resulting in significant cost savings, and makes it ideal for circuits subject to temporary motor overloads and surge currents in industrial and commercial applications.
